Description

Technical Field

[0001] The invention relates to the technical field of fixed bed reactors, in particular to a partitioned fixed bed reactor. Background Art

[0002] A fixed bed reactor refers to a reactor in which a granular solid catalyst or solid reactant is loaded to form a stacked bed layer of a certain height. The gas or liquid material flows through the static fixed bed layer through the gaps between the particles to realize the reaction process. Fixed bed reactors are divided into adiabatic fixed bed reactors, heat exchange fixed bed reactors, tubular fixed bed reactors and multi-stage fixed bed reactors according to the internal reactants and the reaction environment. In exothermic reactions such as ammonia synthesis, methanol synthesis and esterification, a large amount of heat is generated during the reaction. If the heat is not discharged in time, the heat will accumulate in the catalyst, which can easily cause the internal lattice deformation of the catalyst and cracking, resulting in the catalyst being unable to catalyze subsequent reactions. Therefore, a heat exchange fixed bed reactor is required to discharge the heat generated inside. In the existing heat exchange fixed bed reactor, when the reactants flow downward along the container containing the catalyst and react, the catalyst located inside the container is difficult to dissipate the heat, resulting in the temperature of the inner catalyst rising and being damaged.

DETAILED DESCRIPTION

[0031] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0032] During an exothermic reaction, heat accumulates in the catalyst, which can easily damage the catalyst and make it unable to catalyze subsequent reactions. Therefore, a heat exchange fixed bed reactor is needed to discharge the heat generated inside. During the reaction in an existing heat exchange fixed bed reactor, when the reactants flow downward along the container containing the catalyst and react, the catalyst inside the container is difficult to dissipate the heat, resulting in an increase in the temperature of the inner catalyst and damage.

[0033] Example 1: A partitioned fixed bed reactor, such as Figure 1-Figure 4As shown, it includes a base 1, the base 1 is fixedly connected to an outer shell 2, the outer shell 2 is composed of two upper and lower conical shells and an annular shell in between, and the inner shell 2 is connected by a fixed column of an annular array, the upper inner shell 2 is fixedly connected to an upper partition 3, and the lower inner shell 2 is fixedly connected to a lower partition 4, the upper partition 3 and the lower partition 4 divide the outer shell 2 into a feed chamber located at the upper part, a heat exchange chamber located in the middle part, and a discharge chamber located at the lower part, the outer shell 2 is fixedly connected to a liquid outlet pipe 5 and a liquid inlet pipe 6 connected to the heat exchange chamber inside the outer shell 2, the liquid outlet pipe 5 and the liquid inlet pipe 6 are connected to an external circulating cooling device for discharging absorbed heat and re-entering the heat exchange chamber to absorb heat, and a uniformly distributed array tube channel 7 is fixedly connected between the upper partition 3 and the lower partition 4, and the upper and lower ends of the array tube channel 7 are respectively connected to the feed chamber and the discharge chamber inside the outer shell 2, so that the reactants in the feed chamber pass through the uniformly distributed array tube channel 7 and react with the catalyst inside the outer shell 2, and finally generate a mixture (a combination of reactants and products, which is hereinafter referred to as a mixture). The three catalytic tubes 8 in the linear array and the three heat exchange tubes 9 in the two annular arrays are alternately distributed, and the catalytic tubes 8 are connected with the three heat exchange tubes 9 in the adjacent annular arrays. The three catalytic tubes 8 in the linear array are each provided with a support grid 10, and a catalyst is placed above the support grid 10. The support grid 10 is used to support the catalyst, and the reactants can pass through the support grid 10. The top and bottom of the outer shell 2 are respectively fixedly connected with a feed pipe 11 and a discharge pipe 12, the feed pipe 11 is connected with the feed chamber, and the discharge pipe 12 is connected with the discharge chamber. A heat dissipation component for accelerating the heat dissipation of the catalyst is provided in the outer shell 2, and a reversing component for changing the flow direction of the heat exchange medium is provided on the outside of the outer shell 2. The catalyst in the tube channel 7 is divided into three sections, so that the mixture is circulated and dispersed to exchange heat with the cold water in the heat exchange chamber, and then the repolymerization and catalyst reaction are carried out to improve the heat dissipation rate of the heat generated by the reaction.

[0034] like Figure 5 and Figure 6As shown, the heat dissipation assembly includes uniformly distributed sliding cylinders 201, the middle part of the heat exchange tube 9 is spherical, the uniformly distributed sliding cylinders 201 are respectively fixedly connected to the middle parts of adjacent heat exchange tubes 9, the sliding cylinders 201 are fixedly connected and communicated with an inner spherical shell 202 located in the middle part of the adjacent heat exchange tube 9, the inner spherical shell 202 is provided with uniformly distributed counter-punching holes 203, the mixture in the heat exchange tube 9 enters the inner spherical shell 202 through the counter-punching holes 203, the sliding cylinder 201 is slidably connected with a piston shaft 204, and the piston shaft 204 is connected to the inner part of the sliding cylinder 201. 04 pushes the mixture in the inner spherical shell 202 to collide with the mixture in the heat exchange tube 9, slowing down the flow rate while changing the contact position between the mixture and the inner wall of the heat exchange tube, so that the mixture can evenly exchange heat with the cold water in the heat exchange chamber of the outer shell 2. A first elastic element 205 is arranged between the sliding cylinder 201 and the adjacent piston shaft 204. The first elastic element 205 is a tension spring, which is used to drive the adjacent piston shaft 204 to reset. A trigger component for pushing all piston shafts 204 is arranged inside the outer shell 2.

[0035] like Figure 1-Figure 4 As shown, the trigger assembly includes a first servo motor 206, the first servo motor 206 is fixedly connected to the top of the housing 2, the output shaft of the first servo motor 206 is fixedly connected to a rotating shaft 207, the rotating shaft 207 is rotatably connected to the housing 2, the rotating shaft 207 is fixedly connected to a gear ring 208 located in the feed chamber of the housing 2, the three catalytic cylinders 8 in a linear array on the same tube channel 7 are rotatably connected to a trigger shaft 209, the top of the trigger shaft 209 is fixedly connected to a first gear 210 located in the feed chamber of the housing 2, the evenly distributed first gears 210 are all meshed with the gear ring 208, the output shaft of the first servo motor 206 drives the adjacent trigger shaft 209 to rotate through the rotating shaft 207, the gear ring 208 and the first gear 210, the trigger shaft 209 is fixed Two groups of first extrusion blocks 211 in a linear array are connected, and each group contains three first extrusion blocks 211 in an annular array. The first extrusion blocks 211 are right-angled triangles, and the short right-angled sides of the first extrusion blocks 211 are in contact with the adjacent trigger shaft 209. The first extrusion blocks 211 in the linear and annular arrays are respectively extruded and matched with the adjacent piston shafts 204. The rotation of the trigger shaft 209 drives the first extrusion blocks 211 to rotate, so that the hypotenuse of the first extrusion blocks 211 pushes the adjacent piston shaft 204, so that the piston shaft 204 slides along the adjacent sliding cylinder 201. When the first extrusion block 211 is separated from the adjacent piston shaft 204, the first elastic element 205 drives the adjacent piston shaft 204 to reset, so that the piston shaft 204 performs linear reciprocating motion along the adjacent sliding cylinder 201.

[0036] like Figure 1 , Figure 2 and Figure 7As shown, the reversing assembly includes a second servo motor 301, which is fixedly connected to the right side of the base 1. The output shaft of the second servo motor 301 is fixedly connected to the second gear 302. The outer part of the housing 2 is rotatably connected to a rotating ring 303. The rotating ring 303 cooperates with the housing 2 to form a water inlet cavity at the bottom and a water outlet cavity at the top. The liquid outlet pipe 5 is connected to the water outlet cavity so that the cold water in the liquid outlet pipe 5 enters the heat exchange cavity of the housing 2 through the water outlet cavity. The liquid inlet pipe 6 is connected to the water inlet cavity. The upper and lower parts of the rotating ring 303 are respectively provided with a water outlet hole 304 and a water inlet hole 305, and the water outlet hole 304 and the water inlet hole 305 are diagonally spaced on the rotating ring 303. The water outlet holes 304 are connected to the water outlet cavity and the heat exchange cavity in the shell 2, and the water inlet holes 305 are connected to the water inlet cavity and the heat exchange cavity in the shell 2, so that the cold water flows diagonally in the heat exchange cavity of the shell 2. The outer part of the rotating ring 303 is fixedly connected with the teeth of the annular array. The rotating ring 303 is transmission-connected with the second gear 302 through the teeth of the annular array. The second servo motor 301 drives the rotating ring 303 to rotate through the second gear 302 and the teeth of the annular array, so that the rotating ring 303 rotates to continuously change the positions of the water outlet holes 304 and the water inlet holes 305, so that the flow direction of the cold water injected into the heat exchange cavity of the shell 2 is always in dynamic change, thereby improving the utilization rate of the cold water.

[0037] When the fixed bed reactor needs to react, the reactants enter the feed chamber at the top of the outer shell 2 along the feed pipe 11, and then enter the evenly distributed tube channel 7 from the feed chamber. The reactants flow downward along the tube channel 7 and contact the catalyst in the catalytic cylinder 8 to produce corresponding products. At this time, the mixture of products and reactants (hereinafter referred to as this name) carries the heat generated by the reaction and moves downward along the tube channel 7 until it enters the discharge chamber at the bottom of the outer shell 2 and is finally discharged from the discharge pipe 12.

[0038] When the catalyst contacts the reactants to generate corresponding products, a large amount of heat will be released. If it is not discharged in time, the high temperature will damage the catalyst and make it unable to catalyze the subsequent reaction. Therefore, when the reactants are injected into the feed pipe 11, cold water is injected into the liquid inlet pipe 6 at the same time. At this time, the cold water enters the water inlet chamber along the liquid outlet pipe 5, and the cold water in the water inlet chamber enters the heat exchange chamber inside the shell 2 along the water inlet hole 305 on the rotating ring 303. The cold water gradually fills the heat exchange chamber inside the shell 2, and at the same time, heat is exchanged with the catalyst and the mixture (a combination of reactants and products) in the tube channel 7. After absorbing heat, the cold water finally enters the water outlet chamber along the water outlet hole 304 on the upper part of the rotating ring 303, and the cold water enters the liquid outlet pipe 5 along the water outlet chamber and is finally discharged into the external circulating cooling device, and enters the water inlet chamber again along the liquid inlet pipe 6 in a low temperature state. In this cycle, the heat generated by the reaction is discharged to avoid damage to the catalyst due to excessive temperature.

[0039] When cold water starts to be injected into the liquid inlet pipe 6, the second servo motor 301 is turned on, and the output shaft of the second servo motor 301 drives the second gear 302 thereon to start rotating, and the second gear 302 drives the rotating ring 303 to rotate synchronously through the evenly distributed teeth, and the rotation of the rotating ring 303 drives the water outlet hole 304 on the upper part and the water inlet hole 305 on the lower part to rotate synchronously, so that the flow direction of the cold water injected into the heat exchange chamber of the shell 2 is always in dynamic change, avoiding the flow direction of the cold water in the heat exchange chamber of the shell 2 being in a fixed state due to the fixed positions of the liquid outlet pipe 5 and the liquid inlet pipe 6, thereby preventing the occurrence of flow dead angles, thereby reducing the rate of heat generated by the cold water absorption reaction.

[0040] When the reactants flow downward along the tube channel 7, they first enter the catalytic tube 8 and contact the catalyst inside it to produce corresponding products. Then the mixture continues to flow downward with heat and is dispersed into the three heat exchange tubes 9 of the annular array. The mixture exchanges heat with the cold water in the heat exchange chamber of the outer shell 2 in the heat exchange tube 9, and then re-polymerizes along the three heat exchange tubes 9 of the annular array to the next catalytic tube 8, and contacts the catalyst of the catalytic tube 8 again to continue the reaction. This cycle is repeated until the mixture enters the discharge chamber at the bottom of the outer shell 2 and is finally discharged from the discharge pipe 12. By dividing the catalyst in the tube channel 7 into several sections, repeatedly dispersing and re-polymerizing the mixture inside it, and exchanging heat with the cold water in the heat exchange chamber, the heat dissipation rate of the heat generated by the reaction is increased, and it is avoided that the temperature is accumulated in the catalyst and cannot be discharged, resulting in increased catalyst temperature and damage.

[0041] When the reactant is injected into the feed pipe 11, the first servo motor 206 is turned on, and the output shaft of the first servo motor 206 drives the rotating shaft 207 to rotate synchronously, and the rotating shaft 207 drives the gear ring 208 to rotate, and the rotation of the gear ring 208 drives the uniformly distributed first gears 210 to rotate synchronously, and the first gear 210 drives the adjacent trigger shaft 209 to rotate, and the trigger shaft 209 drives the linear and annular array of first extrusion blocks 211 thereon to rotate synchronously, and the first extrusion blocks 211 rotate to extrude the adjacent piston shaft 204, and the piston shaft 204 is subjected to the extrusion force along The adjacent sliding cylinders 201 slide to inject the mixture in the sliding cylinders 201 into the adjacent inner spherical shell 202, and the mixture enters the middle of the heat exchange tube 9 along the counter-punch holes 203 evenly distributed on the inner spherical shell 202. The mixture discharged from the counter-punch holes 203 and the mixture flowing in the heat exchange tube 9 are counteracted, which delays the flow speed and changes the contact position between the mixture and the inner wall of the heat exchange tube 9, so that the mixture can evenly exchange heat with the cold water in the heat exchange cavity of the outer shell 2, further discharge the heat generated by the reaction, and prevent the catalyst from being damaged by high temperature.

[0042] This cycle is repeated until the reaction is completed, and then the injection of reactants into the feed pipe 11 is stopped, and the injection of cold water into the liquid inlet pipe 6 is stopped, and the first servo motor 206 and the second servo motor 301 are turned off. When the reaction is required again, the above steps are repeated.

[0043] Embodiment 2: Based on embodiment 1, Figure 8 and Fig. 9 As shown, it also includes a shaking material assembly that is evenly distributed and used to accelerate the discharge of the catalyst temperature on the adjacent support grid plate 10. The shaking material assembly is arranged inside the adjacent catalytic tube 8. The shaking material assembly includes a shaking material shell 401, which is fixedly connected to the middle part of the adjacent support grid plate 10. The support grid plate 10 is slidably connected to the adjacent catalytic tube 8. A second elastic element 402 is arranged between the support grid plate 10 and the adjacent catalytic tube 8. The second elastic element 402 is a tension spring. The second elastic element 402 is used to drive the adjacent support grid plate 10 to reset. A slide groove 403 is arranged inside the shaking material shell 401. The slide groove 403 is screwed The spiral groove and the straight groove are connected end to end, and the trigger shaft 209 is fixedly connected with a block 404. The block 404 is slidably connected to the slide groove 403 in the adjacent shaking shell 401. The block 404 slides along the spiral groove of the slide groove 403 through the shaking shell 401 to drive the adjacent support grid 10 to move upward. At the same time, the block 404 slides along the straight groove of the slide groove 403, so that the second elastic element 402 drives the support grid 10 to reset. By resetting the support grid 10 before the catalyst, the catalyst is in a short suspended state, which increases the gap between the catalysts, making it easier for the mixture to take away more heat generated by the reaction when it moves downward.

[0044] like Figure 8 and Fig.10As shown, it also includes a stirring assembly that is evenly distributed and used to make the catalyst react evenly. The stirring assembly is arranged inside the adjacent catalytic tube 8. The stirring assembly includes a fixing frame 501, and the fixing frame 501 is fixedly connected to the outside of the adjacent trigger shaft 209. The fixing frame 501 is located inside the adjacent catalytic tube 8. The fixing frame 501 is hinged with two stirring shafts 502 distributed in a mirror image. A third elastic element 503 is arranged between the stirring shaft 502 and the adjacent fixing frame 501. The third elastic element 503 is a torsion spring. The third elastic element 503 is used to drive the adjacent stirring shaft 502 to reset. The inner top of the catalytic tube 8 is fixedly connected to a fixing ring 504, and the inner side of the fixing ring 504 is fixed The six second extrusion blocks 505 are connected in an annular array. The second extrusion blocks 505 are isosceles triangles. The bottom of the second extrusion blocks 505 fits with the adjacent fixed ring 504. The six second extrusion blocks 505 in the annular array are all extruded and matched with the two adjacent stirring shafts 502 distributed in a mirror image. The hypotenuse of the second extrusion block 505 pushes the adjacent stirring shaft 502, so that the stirring shaft 502 is deflected along the adjacent fixed frame 501 by the thrust, and the stirring angle of the stirring shaft 502 to the catalyst is changed, so that the stirring shaft 502 uniformly stirs the catalyst on the supporting grid plate 10, increases its contact area with the reactants, and increases the reaction rate. The interior of the catalytic cylinder 8 is provided with a vibration component for vibrating the catalyst.

[0045] like Fig.10 and Fig.11 As shown, the vibration assembly includes six third extrusion blocks 506 in an annular array, the six third extrusion blocks 506 in the annular array are located above the adjacent second extrusion blocks 505 in the annular array, the lower plane of the third extrusion blocks 506 is a V-shaped arc surface, the six third extrusion blocks 506 in the annular array are fixedly connected to the adjacent fixed collar 504, the interior of the stirring shaft 502 is fixedly connected to the fixed ring 507 in the linear array, the stirring shaft 502 is slidably connected to the push rod 508, the push rod 508 is fixedly connected to the impact disk 509 in the linear array, the impact disk 509 in the linear array is respectively in contact with the adjacent and upper fixed rings 507, and the push rod 508 drives the impact disk 509 to impact the upper adjacent fixed ring 507. The fixed ring 507 causes the adjacent stirring shaft 502 to generate a vibration force, further enhancing the motion state of the catalyst, increasing its contact area with the reactant, and allowing the reaction to proceed evenly. The fixed rings 507 of the linear array are alternately distributed with the impact disks 509 of the adjacent linear array. A fourth elastic element 510 is provided between the impact disk 509 and the adjacent and lower fixed ring 507. The fourth elastic element 510 is a spring. The fourth elastic element 510 is used to drive the adjacent impact disk 509 to reset. The third extrusion blocks 506 of the annular array are all extruded and matched with the adjacent mirror-distributed push rods 508. The push rods 508 slide along the waist of the third extrusion blocks 506, so that the push rods 508 slide along the adjacent stirring shaft 502.

[0046] When the reactants react in the catalyst in the catalytic cylinder 8, the rotation of the trigger shaft 209 will drive the block 404 in the linear array thereon to rotate synchronously. The block 404 rotates and slides along the slide groove 403 in the adjacent shaking shell 401. At this time, the block 404 is located at the top of the spiral groove of the slide groove 403. The rotation of the block 404 drives the adjacent shaking shell 401 to move upward. The shaking shell 401 drives the adjacent support grid 10 to move upward synchronously. The upward movement of the support grid 10 drives the catalyst above it to move synchronously. At the same time, the second elastic element 402 is stretched, so that the block 404 slides to the bottom of the spiral groove and enters the straight groove. At this time, the second elastic element 402 pulls the support grid 10 to quickly reset, so that the block 404 slides along the straight groove to the top of the spiral groove. At this time, the catalyst located above falls downward only due to gravity. The reset speed of the support grid 10 is faster than the falling speed of the catalyst, so that the catalyst is in a suspended state for a short time, increasing the gap between the catalysts, so that the mixture can take away more heat generated by the reaction when moving downward, protecting the catalyst from damage.

[0047] When the reactants react on the catalyst in the catalytic cylinder 8, the trigger shaft 209 rotates and drives the fixed frame 501 thereon to rotate at the same time, and the fixed frame 501 drives the two stirring shafts 502 distributed in the mirror image to rotate synchronously. At this time, the second extrusion block 505 of the annular array squeezes the top of the two adjacent stirring shafts 502 distributed in the mirror image, and the stirring shaft 502 is deflected along the adjacent fixed frame 501 by the extrusion force. At the same time, the two third elastic elements 503 distributed in the mirror image accumulate force. When the stirring shaft 502 rotates to the top angle of the adjacent second extrusion block 505, the third elastic element 503 is reset and drives the adjacent stirring shaft 502 to reset until the stirring shaft 502 is separated from the adjacent second extrusion block 505. When the stirring shaft 502 contacts the second extrusion block 505 again, the above steps are repeated. The stirring amplitude of the catalyst is continuously changed by the stirring shaft 502, so that the stirring shaft 502 evenly stirs the catalyst on the supporting grid plate 10, thereby increasing its contact area with the reactants and increasing the reaction rate.

[0048] When the stirring shaft 502 rotates, the stirring shaft 502 drives the push rod 508 inside it to rotate synchronously. At this time, the third extrusion block 506 of the annular array squeezes the adjacent push rod 508, and the push rod 508 slides downward along the adjacent stirring shaft 502 due to the extrusion force. The push rod 508 drives the impact disk 509 of the linear array thereon to move synchronously. At this time, the adjacent fourth elastic element 510 is compressed. When the push rod 508 slides to the lowest end of the V-shaped arc surface on the adjacent third extrusion block 506, the fourth elastic element 510 of the linear array is reset and drives the impact disk 509 to impact the adjacent fixed ring 507, so that the fixed ring 507 is driven by the impact force to drive the stirring shaft 502 to generate a vibration force, and then the stirring shaft 502 transmits the vibration force to the catalyst when stirring the catalyst, so that the catalyst generates a vibration force while being stirred, further enhancing the motion state of the catalyst, increasing its contact area with the reactants, and making the reaction proceed evenly.
